my 03 tahoe passenger door controls are all dead, door lock, window, keyless entry doesnt work either but all other doors are fine. anyone have an idea of whats wrong?

 

Probably the wires wore out that go through the 'pass-thru' from the body to the door. All the constant opening and closing of the door finally took its toll on the wires as they were bent back and forth over time. I'd check there for broken wires first.

 

Theres a 25 amp silver fuse in the fuse box located in the truck that may cause it (happened on mine) also the switches themselves might have gone out also happened on mine got another assembly from a salvage yard works like a champ again.

 

the wires to the door are fine so i will look for the fuse tommorow
